ISP620-1 Equivalent & Substitute Parts

Part Overview

The ISP620-1 is an optoisolator with transistor output, rated for 5300Vrms isolation voltage in a 4-DIP package. This component provides galvanic isolation for AC and DC input signals with a single output channel. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required for procurement flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISP620-1 are qualified based on the following electrical and mechanical parameters:

• Isolation Voltage: 5300Vrms (exact match required)
• Number of Channels: 1 (exact match required)
• Output Type: Transistor (exact match required)
• Package / Case: 4-DIP (0.300", 7.62mm) (exact match required)
• Current Transfer Ratio Range: 50% (Min) to 600% (Max) @ 5mA (exact match required)
• Maximum Output Voltage: 55V (exact match required)
• Maximum Output Current: 50mA per channel (exact match required)
• Vce Saturation: 400mV maximum (exact match required)
• Operating Temperature Range: -30°C ~ 100°C (exact match required)
• Input Type: AC, DC (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria without deviation.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ISP620-1, ISP620-1X, and TLP620X—are active production components with identical electrical specifications and mechanical compatibility. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. All parts carry ROHS3 compliance and are suitable for applications requiring 5300Vrms isolation with single-channel transistor output in 4-DIP through-hole packages.

Frequently Asked Questions (FAQ)

Q: Can ISP620-1X be used as a direct replacement for ISP620-1?

A: Yes. ISP620-1X meets all electrical and mechanical parameters of ISP620-1, including isolation voltage, current transfer ratio, output specifications, operating temperature range, and package configuration.

Q: Is TLP620X electrically equivalent to ISP620-1?

A: Yes. TLP620X provides identical electrical performance across all specified parameters: 5300Vrms isolation, 1-channel transistor output, 50% to 600% current transfer ratio, 55V maximum output voltage, and 50mA output current per channel.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use the 4-DIP (0.300", 7.62mm) package with through-hole mounting, ensuring mechanical and pin compatibility on identical PCB designs.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status.

Q: Are there differences in input type between these parts?

A: No. All three parts accept both AC and DC input signals with identical specifications.
